Short Content: System synopsis    This system's major function is through carries on the compression to the voice signal, realizes the high efficiency digit sound recording, may use in the telephone message, situations and so on sound of talking reply. Uses the tape recording to realize the telephone message, although records the time is long, but is not advantageous for the search and the preservation. The digital sound recording may overcome the tape recording the shortcoming, not only the seek rate is quick, ...

Short Content:     The FIR filter's structure main right and wrong recursive structure, has not output the input the feedback. And the FIR filter are very easy to obtain the strict linear phase characteristic, avoids processing the signal to produce the phase distortion. But the linear phase manifests in the time domain is merely h (n) in the time detention, this characteristic in profile transmission systems and so on image signal processing, data transmission is very important. In addition, he will not ...

Short Content: 1 TMS320C5402 MCBSP working　　MCBSP is the TMS320C5402 multichannel cushion serial port (MCBSP0 and MCBSP1). MCBSP exterior is connected through 6 base pins and other serial components, in internal and DSP essence connection. The serial data receiving and dispatching base pin and the internal each serial port register are connected.　　According to the MCBSP function and the structure, may its working summary be: SPI working and multichannel cushion working.　　This article mainly introduces the SPI operating mode. The MCBSP exterior base pin is: ...
